Trimix diving with v planner

[padiscubapro]

andibk once bubbled...
List,

This is the dive profile I was thinking of doing. I have a copy of the GAP, ANDI, Voyager, pro planner and a Sheck Exley plan and they all give some what similiar profiles. The V planner give the shortest run times but do alot deeper stops. I have used v planner on nitrox dives but nothing with trimix. Is this v planner similiar to the GUE profiles. I would feel a whole lot better knowing if others are doing these profiles then being a human ginny pig myself.

I would change a few things.. by switching to no helium at 40m you are putting in a huge gradient so the tables generated will be very short.. I know on dives that I had a high PHe and switched totally off, I didn't feel as good as I did when doing an intermediate step..

instead of nitrox 32 use
32/32 trimix then switch to 50% at 22m, These schedules should be much closer in line to what you are used to.. I run Vplanner with a +2 without any ill effects.. Since I started diving exclusivly on a CCR(and dont do a diluent flush with a gas without He), I don't get that huge gradient change all at once, I feel great, and have a slightly longer deco using VPM but still faster than other tables.
